Answer:
The height of the object at t=7 seconds is 336 feet.
Step-by-step explanation:
Given,
An object is dropped from the top of a tower with a height of height of 1120 feet.
The height of the object at time t second is given by the polynomial
h(t)= -16t² +1120
To find the height, we put the value of t=7 in the above equation
h(7)= - 16(7)²+1120
= 336 feet.
The height of the object at t=7 seconds is 336 feet.
Answer:
Height of the object after 7 seconds would be 336 feet.
Step-by-step explanation:
Given:
Height of the tower = 1120 ft
[tex]h(t) = -16t^2+1120[/tex]
We need to find the height of the object after 7 seconds.
Solution:
To find the height of the object after 7 seconds we will substitute t = 7 secs
So we can say that;
[tex]h(7) = -16(7)^2+1120 = -16\times 49 +1120 = -784+1120=336\ ft[/tex]
Hence We can say that;
Height of the object after 7 seconds would be 336 feet.
